The on-again, off-again deal with the Boston Celtics acquiring Kevin Garnett apparently is back on.

According to sources, the current deal on the table has the 6-foot-11 Garnett heading to Boston and the Celtics dealing away Al Jefferson (above), Theo Ratliff’s hefty expiring contract and Rajon Rondo. There may also be other players and draft picks involved.

The deal would give Ainge a team that could compete with anyone in the Eastern Conference with the trio of Paul Pierce, Garnett and Allen. The Celtics would also have nearly $60 million in salaries between the three players for next season alone.

The Wolves would get one of the league’s top young players in the 22-year-old Jefferson, who averaged 16 points and 11 boards in 69 games a year ago, and a second-year point guard in Rondo with plenty of potential. They would also get Ratliff’s $11.7 million salary, which will come off the books after this season.
